How to Fix Gtgina.dll Log on and Fast User Switching Problems

Many users who have recently purchased and installed a Linksys Compact Wireless-G USB Adapter, WUSB54GC, on a Windows XP based machine, may have experienced Fast User Switching being disabled.

Many users wondered what the issue was and traced the problem to WUSB54GC. Linksys has said that the installation of the Linksys Wireless Network Monitor software will automatically disable both the Windows XP Welcome Screen and Windows XP Fast User Switching.

This is caused by an incompatibility between Fast User Switching and LEAP security. For Windows login account information to be linked to LEAP security, Fast User Switching must be disabled.

This has irritated myriads of users who prefer to use or need to use the Fast User Switching of Windows XP which has been disabled by GTGina.dll.  Linksys advises that the registry entry for GTGina.dll to be kept and should not be removed. Incorrectly removing the file from the registry may lead to boot up issues.
